Hello everyone!

 

Started a service on my next movement and I am hoping someone has a link for a service / parts sheet for the 29C UT movement. This will be my first movement with the date complication. I currently have the movement disassembled, Pegged out, ran through the cleaning machine and ready for reassembly. I have looked on the Raniff site and found very limited information, Cousins UK didn't have any information either.

So I have a question in regards to replacing the end stones on the pallet fork, I'm not sure what this system is. I was able to remove it using the same process as the Inca bloc setting. But for the life of me I can't get it back in the movement. I pinged it away a couple of time but was able to locate the retention spring. It is the type that looks like a U with a tab at the bottom and the two legs curve out. There in no cut away like with some other end stone settings which is making this a task to say the least. Any help / advise would be appreciated.

Sanity check your movement against pics of the Seiko 66 but Universal Time was an offshoot of Seiko. If yours has a date then it would be the Seiko 6602B variant specifically ... and Cousins has that download.

Thank you I'll have a look again on Cousins with the Seiko number.

Please post pictures of both the spring and the setting so to be sure what is that you have. 

However it could be done with two tweezers, one holding the U and tab in place, the other easing the legs in, one at the time.

Watchmaker, 

Just off the Cousins site and there is no download for the 66028, the search brings up two omega downloads.

So the first photo is the setting that I am trying to replace the end stone into, the second is the end stone and retainer, the third picture shows the setting complete on the other side of the mainplate. These are for the escape wheel.

Hi @EdB. It's here: https://www.cousinsuk.com/PDF/categories/3111_Seiko 6602B.pdf

[That's a 'B' at the end of the movement ID; you misread as an '8'].

To support the statement you're dealing with a Seiko based movement that's a Seiko Diafix shock spring you have there! With that knowledge if you do a web search, or look on YouTube, you'll find info on how to deal with one.

      AS2063 - hand setting

      By Mercurial · Posted

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?

      The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem.

      Balance staff sourcing?

      By mthomas828 · Posted

      Hello, I am about 5 months into watchmaking and I love it!   The attention to precise detail is what really attracts me to it. (and the tools!) I am working on a 16 jewel 43mm pocket watch movement.   There are no markings besides a serial number (122248) .  The balance staff needs replacement. The roller side pivot broke off.  I successfully removed the hairspring using Bergeon 5430's.  I successfully removed the roller using Bergeon 2810.   Did i mention I love the tools?! I removed the staff from the balance wheel using a vintage K&D staff removal tool  with my Bergeon 15285 (that's the one that comes with a micrometer adjustment so it can be used as a jewel press as well as a traditional staking tool...it's sooooo cool...sorry..  can you tell i love the tools?) No more digressing..  I measured the damaged staff in all the relevant areas but I have to estimate on some because one of the pivots is missing. A = Full length  A= 4.80mm  (that's without the one pivot...if you assume that the missing pivot is the same length as the other pivot (I'm sure it's not)  then A = 5.12 mm...(can I assume 5.00mm here?) F=  Hair spring collet seat  F=  .89mm   (safe to assume .90 here? .. I am sure that my measurement's would at least contain  .01 mm error ?) G = balance wheel seat  G = 1.23 mm  (1.20mm?) H  =  roller staff  H =  .59mm  (.60 mm?) B  = bottom of the wheel to roller pivot   B  = 2.97mm  (3.00 mm?)     here I am estimating  again because this pivot is missing. So my friends, and I thank you profusely,  can you point me in the right direction as to how to proceed? Do i buy individual staffs?  or an assortment?   Since I don't know exactly the name of the manufacturer, will that be a fatal hindrance?   Tbh, I'm not even sure what country of origin this movement is. Thank you!

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Thats why i asked that question earlier, what happens if lubrication is placed directly on top of epilame ?  As opposed to walled within its non epilamed area . I'm not saying its right, i have no idea , just asking questions.
